Y COMBINEDRANGE A'ND WATER-HEATER.

sPEcIrcA'rIoN forming part of ilettlslratent No. 702,343, dated Juli 1o, 1902.

Application tied January 31,190a Seriana. 92,013. (tympan.) p

To a/ZZ whom, t may concern,.-

of Boston ,in the county of Suffolkand State of Massachusetts,have invented certain newand useful Improvements in a Combined Range.

and Water-Heater, of which the following is a specification.

This invention relates to ranges or cook-i-ngstoves having provisions. for .supplying .hot-

Water to be circulated through a house-or apartment, so as to heat the same.

The object of the invention is to provide a simple, practical, and durable device of this character which can readily be arranged for Winter or summer use, as Will appear hereinafter.

Of the accompanying drawings, Figure 1 represents a front elevation of a Acombined range and water-heater constructedin acji cordance with m invention Fig. 2 re resents a longitudinal verticalfsection thereof. Fig. 3 represents a section on line 3 3 of Fig.

1. Fig. 4 represents a section online 4 4 of The same reference characters-indicate the same parts in all the iigures.

In carrying out my invention I provide the range with two fire chambers 1 2, having grates 3 4 in their lower portions arranged above ash-pits 5 6, and a Water-chamber 7, disposed principally above the fire-chamber 1, but having vertical legs,89 10.11` 12, which form Water-walls for the sides of both charnbers 1 and 2. The water-leg 9 forms a yer` tical waterpartition, separating the iirechambers 1 and 2. The upper part of chamber 2 is provided with a refractory lining 13 of fire-brick and a removable upper gratef14 to support a iire in said upperprtionfor summer use. The portion 24 of said chamber-2 aboye the grate 14 may be ,considered as a fire-chamber extension, through which the gases pass to the uptake by wayof passage 16, hereinafter mentioned.

15 is the top of the range, provided with the usual pot-holes and lids and serving as a support forcooking utensils. This top is separated from the water-chamber 7 by a substantially horizontal passage 16, which carries the products of combustion from both nre-chambers to a stack or uptake 17. Said products also pass around or over an oven 28,`which v l may be locatedinlanysuitable position other Be it knownfthatLHARRIsoN W. CONNER,

than that shown. The fire-cham ber l has connection with the passage 16 "by'way of a series of substantially vertical iues or tubes 1S '18, and the fire-chamber 2 has 'direct connectionthrough its upper end with said passage.

. 23 is a larger hole traversing the waterchamber-7for the introduction of fuel to the .grate 3 andthe passageo gases.

It will be seen that the fire-chamber l is primarily assigned to the heating of the water-chamber 7, though it also serves in part 4to heat the stove-top 15 and the oven. The principal'function of the tire-chamber 2 is to heat thestove-top 15 and the oven for cooking purposes; but its lower portion is also disposed in heating relation to the waterchamber 7. In winter, when the Water-heat is desired inthe house or apartment, the up- ,per' grate14 in the fire-chamber 2 is` prefer- `ablyaemoved,and tires are 4built on the two lower grates 3 4, thefire on the grate 3 serving in the manner described principally to heat Vthe4 water-chamber and the iire on the grate 4 being used for cooking purposes, although it willbe understood that a lesser heating effect on the water in the water-chamber 7 may be obtained by building the fires on the gratos 3 and 14. In summer, when hot-water heat is not desired, a single re only is builton'the grate 14, the refractory lining 13 serying to protect the walls of said `water-chamber from the heat of the re on said grate. When res are built on the grates 3 and 4, the metal walls of the water-legs 8 9, dac., are protected by the water in said legs, making a refractory lining necessary on these 'portions'.l AI`may, however, While retaining the Water-leg 9, separating the two fire-chambers, omit one or more of the water-legs 8 `10 11 12.

Access is had to the fire-chambers 1 2 for coaling or other purposes .either through doors 19 2O in their ends or throughlthe potholes in the stove-top 15,.

21 22 are returnand supply pipes for circulating the water from the heater and through the house-heating system.

I claim- 1. A combined cookingstove and waterheater having a top or support for utensils, a water-chamber separated therefrom by a IOG lower gratos arranged in a tier, the lower' grate being in direct heating relation to the voasiie walls of said chamber and the space which said grates occupy having an outlet to said passage, a refractory lining forming the Walls of said space abovethe upper grate, and a third grate positioned to one side of said grat-es and in heating relation to said chamber, the space which it occupies having a separate outlet for gases.

In testimony whereof I have affixed my signature in presence of two Witnesses.
